A sudden storm.
Sideways wind, sheets of rain hitting the house, the trees bending over, rain spraying every surface, leaves flying about, the gutters gushing full...
And then it's gone, and then this:
an impossibly beautiful rainbow, a golden sunset, and when I turned back around--the sky's colors had changed already, and the rainbow was still unmistakeable.
So always, always look up, rather than down.
